APFS disk container error

[rondaemond]

Hi, need some help here...
I have a 2012 MacBook Pro with 1Tb SSD HD.
A few days ago it stopped booting. I tried everything (PRAM RESET, Recovery booting, etc) but nothing worked.
I have very important information on the SSD drive... and guess what... I lost my back up...
I managed to install High Sierra on a different drive and use my SDD drive in a usb case. But I cannot see it in Finder, Disk Utility cannot mount it or repair ir, and Terminal shows:

dev/disk2 (external, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *1.0 TB disk2

1: EFI EFI 209.7 MB disk2s1

2: Apple_APFS Container disk3 1000.0 GB disk2s2


/dev/disk3 (synthesized):

#: TYPE NAME SIZE IDENTIFIER

0: APFS Container Scheme - +ERROR disk3

Physical Store disk2s2

It seems that somehow I need to restore the container.... or something like that.

Can somebody help me??? I'm just about to format and resign all the files missed...
Thanks in advance

Looks like it's gone.

Only the brave, devs and foolhardy should use first generation file systems.
But i guess Apple have to throw us into the deep end sometime.
I might give High Sierra a go now that it's been a few months.

Yeah, It was gone. I could recover some information using disk drill.
It looks like a hardware issue, because I installed Mac OS Sierra in my old 750 GB HD and it's still working very slow and laggy.
I checked RAM, hard disks and everything was OK.

Don't know what could it be.

Try posting your problem in the "High Sierra" forum, users over there might be more knowledgeable about APFS and it's possible problems.

UPDATE
Finally I was able to find the problem.
It seems that MacBooks Pro mid 2012 (pre retina) have some kind of design failure issue. Sooner or later it will affect yours.
This video explains it very simple

I bought a 10 USD SATA replacement cable at amazon, changed the old one and did what the video recommends.
My macbook started working fine again... I lost my data (I was able to recover most of it), but my computer stopped lagging and now is working perfect with my SSD HD.

Im posting this because I've seen lot of people with similar problems, but the solution was not easy to find.
